I can only comment on my recent memory. But it seemed in 2008, every time Sheets tried to come back, his elbow hurt, or his shoulder hurt, or he had a problem with his finger. Seems like something was always happening and seems extremely injury prone if you ask me. Sure I'd love a healthy Sheets, but I don't think we'll get that. When was the last time he was fully healthy or atleast mostly healthy? Sheets healthy for a third or half of the season at 5-6MM is a much better option than Silva starting and having another bullpen lackey being on the roster for that same period of time.
